Application filed September 11, 1905. Serial No. 277,893.

To all whom it may concern/i Be'it known that I, FRED W. TOBEY, a

citizen of the United States, residing at Grand Rapids, in the county ofKent and State of Michigan, have invented certain new and useful Imrovements in Type- Writer Cabinets and do hereby declare the followingto be a full, clear, and exact de' scription of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to improvements in type-writer cabinets, and moreparticularly to such cabinets having an inner chamber in which is amovable platform to support the type-writer, and above which chamber isa movable cover connected to the platform,

whereby when as the cover is opened and closed the platform is raisedand lowered; and 1 its object is to )rovide the device with improvedmeans or connectlng the latform and cover, to provide means for 100 mgthe cover and platform in open position, and to provide the device withvarious new and useful features hereinafter morefully described, andparticularly pointed. out in the claims, reference being had to theaccompanying drawings, in which Figure 1 is a-vertical section of adevice embodying my invention, showing the same in closed position Fig.2, a perspective view I of the same; and Fig. 3, a vertical section ofthe same, showing the device in open position in solid lines and inpartially-opened position in broken lines.

Like numbers refer to like parts in all of the figures. l The case is inthe usual form ofa desk or table, as may be preferred, and having achamber in its interior to contain the typewriter and itssupporting-table. This chamber is closed at the sides bythe usual chestsof drawers or other receptacles, and the bottom of the chamber isprovided with a closure 7, preferably an open frame, and a concave front6, which bottom and front are spaced apart from the sides of the.chamber and supported at the front by a metal bracket 16 and at the rearby the back of the case to permit the passage through said space of thevarious connecting-rods and levers to support and operate the platformfor the type-wrlter.

In the preferred form shown the movable part of the top consists of twoseparate sections'-a front sect-ion 1, hinged at the rear to theintermediate section, as at 3, to which is attached adownwardly-extended apron 5, forming a art of the front of the case whenclosed, an an intermediate section 2, hinged to the stationary part ofthe top at its rear, as at 4. I v

8 is a movable platform on which the typewriter is supported. Thisplatform is carried upon four-parallel arms 9 and 10, pivoted at one endto the platform near its respective corners and at the other end to thesides of the chamber of the case and extending through the s ace betweenthe bottom 7. and concave 6 an said sides of the chamber and adaptedtojturn to a vertical position when the device isopen for use and toturn rearward and downward to ether with the platform when the device isc losed.

Q To operate and adjust the arms and plat form, leversll are pivoted atone end to the side walls of the case and connected at the other end byrods 12 to the arms 10, and from the levers 1 1 other connecting-rods 13extend upward and are connected to short arms 14,

rigidly attached to the section 2 of the top.

'Near the rear of the platform}; is an upwardly-projecting stop 15,adapted to engage the lower edge of the apron 5 when the device is open,and thus lock the device in open position until .the front edge of thesection 1 is lifted to release the same.

The hinge 3 being on the under side of the parts 1 and 2 forms' arule-joint between these parts, ,Whereby when the front edge of thesection 1 is lifted to open the device the sections 1 and2 form a leverturning on the pivot formed by the hinges 4, the arms 14 thus formingthe other member of a bell crank lever, whereby through the rods 13,levers 11 and rods 12 the arms 9 and 10 are turned from the rearwardly-inclined position to vertical position, and thus carry theplatform Sin a horizontal position upward and forward to position forusing the type-writer, as shown in Fig. 3. When the device is nearlyopen, the front part 1 can be turned downward and forward and theopening process completed by pushing theupper part of the section 2backward to open position, as indicated in Fig. 3. When the front of thepart 1 is lowered to place and. the apron 5 en aged by the stop 15, thedevice not only is 100 red in open position,

but the entire section 1 is in horizontal and proper positionto be usedas an elevated ta ble at the rear of the type-writer, and the apron 5closes the space between the section sure'of the chamber below andpreventing anything from falling into the same.

planes with the middle part inverted, and an apron on the front of thecover adapted to engage the stop to lock the device with the platformelevated and the cover open.

2. In a type-writer cabinet, a case having an inner chamber, a platformmovable in the chamber, means for movably supporting the platform, astop on the platform, a cover to the chamber and having a hinged rearportion'adaptedto turn to reversed horizontal positions, and a frontportion hinged thereto to move rearward Without reversing, an apron onthe cover to engage the stop, and means for connecting the rear portionof the cover and said platform-supp orting means to simultaneouslyadjust the cover and platform.

3. In a type-writer cabinet, a case having p Witnesses:

an inner chamber, a platform movable in the chamber, means forsupporting and moving the platform, a cover for the chamber divided intofront, middle, and rear parts, said parts bei hinged to each other, therear part bemg turn to reversed horizontal positions, the front partbeing moved rearward thereby without reversal, a bottom in the chamberhaving an upwardly-extended front portion, and an apron on the frontportion of the ed, the middle part being adapted to cover adapted toengage the front of the bottom when the device is closed, and to engagethe rear of the platform when the device is open.

4. tion of a case having an inner chamber, a platform movable in thechamber, parallel arms pivoted to the platform atone end and In atype-writer cabinet, the combingto the sidesof the chamber at the otherend, a

cover havin a hinged portion adapted to turn to reversed orizontalpositions, a rigid arm on said portion, a toggle-joint lever pivoted atits respective ends tov one of the parallel arms and to the case, and arod connecting,

the said lever and the arm on the cover. In testimony whereof I aflix mysignature in presence of two witnesses.
